Which stain is used to demonstrate ring sideroblasts?

Detecting iron deposits in developing red blood cells is what reveals ring sideroblasts. These are erythroblasts whose mitochondria accumulate iron around the nucleus, forming a blue ring when iron is stained. The Prussian blue (Perls) stain specifically detects ferric iron by reacting with it to form blue ferric ferrocyanide, highlighting those iron-containing rings around the nucleus. That makes Prussian blue the stain of choice for demonstrating ring sideroblasts. The other stains are used for different purposes: Wright and Giemsa stain general cell morphology, while Sudan Black targets lipids in granulocytes and does not reveal iron deposits.
